Embodiment Construction

[0020] A method for realizing cable electromagnetic compatibility, characterized in that, said method for realizing electromagnetic compatibility comprises the following steps:

[0021] S1: Peel off the outer rubber of the cable at the place where the cable enters and exits the device;

[0022] S2: Put the sealant rubber sleeve on the peeling part of the cable, and the rubber sleeve is required to form an interference fit with the outer rubber layer of the cable, the cable shielding layer and the casing.

[0023] In this embodiment, the method for realizing cable electromagnetic compatibility is characterized in that the front and rear of the rubber sleeve are respectively unilaterally interference fit with the rubber circumference of the cable by 0.15-0.25mm to achieve a waterproof seal Function: The middle step of the rubber sleeve and the circumference of the cable shielding layer have a unilateral interference fit of 0.15-0.25mm, and the surroundings of the rubber sleeve a...

Abstract

A method for realizing cable electromagnetic compatibility, comprising the steps of peeling off the outer rubber of the cable at the place where the cable enters and exits the device; putting a special electromagnetic shielding rubber sleeve on the stripped part of the cable, requiring the rubber The sleeve forms an interference fit with the outer rubber of the cable, the cable shielding layer and the casing. By using multi-layer shielding media, the electromagnetic shielding effect of the cable itself is improved; the electromagnetic noise coupled to the cable shielding layer when the device is working can be directly introduced into the chassis ground, and it also prevents the electromagnetic noise in the machine from passing through the gap between the cable and the chassis And radiate out. Improve the electromagnetic compatibility performance of the equipment, increase the pass rate, shorten the equipment development cycle and reduce the development cost.

Description

technical field [0001] The invention belongs to the field of electric power and communication transmission, and in particular relates to a method for realizing cable electromagnetic compatibility. Background technique [0002] Electromagnetic compatibility requirements are currently the most important experimental requirements in the military equipment industry. In order to meet the electromagnetic compatibility performance of equipment, R&D personnel often invest a lot of research and development time and funds in design and experimental verification. The reason why the EMC test fails is mainly because the electromagnetic noise inside the machine is coupled and emitted by the cable of the whole machine, so the cable itself has strong shielding performance and the equipment is well sealed, which can significantly improve the EMC performance of the whole machine. Contents of the invention [0003] The object of the present invention is to propose a method for realizing cabl...
